LED LIGHTING












LED lighting is the new energy wave of the future. Exterior and interior general illumination, safety and security, general production and service lighting uses are just some of the financial energy savings that local businesses and municipalities can benefit from. By converting to LED lighting, we can reduce energy use and energy costs, improve light pollution and light quality and improve where light is directed. Now is an excellent time for businesses and municipalities to consider converting to LED lighting and reap these benefits.

We’ll schedule a visit to your facility, conduct a free lighting audit, define you’re lighting problems and review all of the LED benefits. We will show you the energy and installation savings you will achieve while filling your buildings with the most beautiful, brilliant white light you’ve ever seen. All with no ballast to fail, no blinking, no bugs, no noxious mercury, no noise, no waiting for lights to restart. And best of all...no maintenance!

D&J Electric has provided a wide-range of Electrical Contracting services. Our goal is simple: provide quality products, workmanship and ensure our customer's complete safety. 


The Future of LED Lighting


The economics of LED lighting makes the technology a compelling one for governments that are struggling to cut expenditures while trying to meet “green” goals. Despite the higher initial investment, switching to LEDs from incandescent lighting can quickly pay off on both fronts, while avoiding the complaints and limitations associated with the compact fluorescent (CFC) bulbs that haven’t quite lived up to their expected potential.

For example, a 2013 New York State Department of Energy Conservation report says that if all state municipalities replaced existing incandescent streetlights with LED bulbs — which are brighter, more energy-efficient and longer-lasting — it would reduce energy consumption by 22.3 million kilowatt-hours annually, while cutting greenhouse gas emissions by 9,200 tons. The switch would also save on maintenance costs since bulbs would require less frequent replacement.

On top of that, the report suggests that switching from traditional mercury vapor streetlights to LED doesn’t just significantly reduce  energy and maintenance costs (a big deal, since street lighting makes up roughly 40% of the state’s municipality electrical bills), but also the number of lamp posts needed is more effective as well.

SmartPlanet profiled an example of LED savings in action, telling the story of a NYC property owner who is retrofitting 21 properties with LED lighting (replacing fluorescent, incandescent and halogen fixtures) for an energy savings of $750,000. Even at the current, high-cost of LED bulbs, the estimated payback on the project is only three years, with the remaining lifespan of the LED bulbs (which should be at least another 10 years) representing pure savings. The story points to LED lighting as “low-hanging fruit” for commercial property owners looking to slash the 25% to 30% of their energy bill that lighting typically consumes.

Plus, the fact that LED lighting is solid-state means it can be controlled by software, leading to a whole new avenue of growth: programmable lighting. This has been on full public display through large scale installations like San Francisco’s Bay Bridge and New York’s Empire State Building, and has begun to catch on at the home level thanks to app-controlled LED lighting systems like Philips’ (NYSE:PHG) Hue wireless system.

 


Benefits of  LED Lighting


LED Lighting is a new technology that promises to replace all other types of lighting by 2020.

In short, it saves 40-90% on lighting, has a very long lifespan, and looks better than other types of lighting and is easily controlled.


Operation  

  1. LED's use far less energy than other lights.

  2. Long lifespan of up to 100,000 hours.(That's 11.4 years of 24/7 usage)

  3. Durable.  Won't break if dropped.

  4. Do not require a ballast.

  5. Stays cool to the touch.

  6. Turns on and off instantly.

  7. Silent.

  8. Most LED's can be dimmed.


Light Quality

  1. Never flicker or blink.

  2. Pure color.

  3. Your choice of Color temperature: warm, natural or cool white.

  4. High color rendering index(CRI) compared to fluorescent.

  5. Very bright for the amount of power used.(Luminous efficacy reaching 100 lumens per Watt.)

  6. No UV radiation.



Environmental Impact

  1. Less energy used means less carbon emissions.

  2. Do not contain mercury.

  3. Do not contain lead.

  4. Made mostly from recyclable materials.


Cost

  1. LED's are expensive, but they will pay off  in about 1-10 years and save tons of money in the long run.

  2. They save money by using 40-90% less energy than other lights.

  3. One LED lamp will last as long as several traditional lights, saving money on replacements.

  4. They don't require any maintenance after they are installed.

  5. Do not add significant heat to the room so they will save money on cooling costs.

  6. Rebates, grants and tax incentives are often available for some projects.


















 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Why SSL


Solid-State Lighting: Brilliant Solutions for America's Energy Future

Energy Savings Potential of SSL

Energy Savings Estimates of LEDs


More Resources

Since 2003, the U.S. Department of Energy has invested with industry partners in research and development of solid-state lighting (SSL)—including both light-emitting diode (LED) and organic light emitting diode (OLED) technologies. Why such concentrated attention on SSL?

The answer is simple: because of SSL's rapid ongoing improvements and superior energy-saving potential. It is estimated that switching to LED lighting over the next two decades could save the country $250 billion in energy costs over that period, reduce the electricity consumption for lighting by nearly one half, and avoid 1,800 million metric tons of carbon emission.1 DOE is not alone in recognizing the importance of that kind of savings; Congress recognizes it too, which is why the Energy Policy Act of 2005 mandates DOE to accelerate SSL technology.

That doesn't mean DOE has abandoned lighting controls and other light source technologies, however. DOE still invests to a large degree in promoting the most efficient forms of conventional lighting technologies, through such implementation programs as Building America, the Commercial Buildings Integration Program, and the Federal Energy Management Program.
















Avoiding the Roadblocks

DOE is keeping a close watch on solid-state lighting, in both the lab and the marketplace, to make sure it doesn't run into the same roadblocks that slowed market acceptance of compact fluorescent lamps (CFLs) back in the 1990s. Accelerating the pace of commercialization for SSL will hinge on improving cost competitiveness and quality.

  1. Improving cost competitiveness. One major roadblock for SSL is cost. Today, the purchase price of LED lighting products is generally higher than that of their conventional counterparts, often by a long shot, and the energy savings often aren't enough to offset the difference within an attractive payback period. However, DOE's program is intended to drive aggressive cost reduction, and the current rate of cost decline in LED lighting systems is about 20 percent a year. Prices will continue to drop before starting to level off.

  2. Improving quality. DOE watches closely for problems with poor-performing SSL products that are not yet ready to compete with incumbent technologies, including products that fail to meet manufacturers' performance claims. A significant part of DOE's function is to educate consumers as well as the lighting community about those claims and other pitfalls in the SSL marketplace. As a government agency serving all U.S. citizens, DOE brings a "just the facts" attitude and an independent, vendor-neutral perspective to solid-state lighting, which is why so many people look to DOE for honest, reliable information.

There's little doubt that solid-state lighting ultimately will emerge as the technology of choice for an unparalleled variety of applications, because, all things being equal, everyone—building owners included—wants to save energy and protect the environment. Meanwhile, all things are not equal, which is why DOE repeatedly emphasizes that SSL is right for some applications but not for others—and why education and due diligence should be key elements in any lighting specification and purchasing process.

A Comprehensive Program

DOE has made a long-term commitment to advance the development and market introduction of energy-efficient solid-state lighting. Its comprehensive national program addresses research and development, demonstrations, testing and quality control, market development support, and buyer support—all in service of maximizing the energy-efficiency of SSL products in the marketplace.

With three annual workshops that collectively bring together approximately 700 attendees, as well as periodic stakeholder roundtables, DOE's solid-state lighting program is open and participatory and coordinates with many lighting and standards groups, such as the Illuminating Engineering Society of North America, the International Association of Lighting Designers, the National Electrical Manufacturers Association, the American National Standards Institute, and the National Institute of Standards and Technology. It's also highly transparent, publishing numerous reports and roadmaps that are posted online at this website.
